ADJUSTABLE SCREEN-DOOR.

SPECIFICATION forming part of Letters Patent No. |771,688, dated October4, 1904. Application file February 6, 1904. Fferial No. 192,333. (Nomodel.)

To (all whom it may concern:

Be it known that I, EBEN P; VVILLIAMS, a citizen of the United States,and a resident of Hyannis, in the county of Barnstable and State ofMassachusetts, have invented certain new and useful Improvements inAdjustable Screen-Doors, of which the following is a specification.

This invention relates to improvements in adjustable screen-doorsadapted for ventilating purposes, preferably adapted for outside doors;and it consists, in combination with a door, of a vertically-adjustableglass-covered frame or sash and a spring-actuated screen or nettingconnected to said sash and means for securing said glass-covered sashand the screen in any desired Vertical position according to the degreeof ventilation desired and means for securing the glass-covered sash ina closed locked position, as will hereinafter be more fully shown anddescribed, reference being had to the accompanying drawings, whereinaFigurel is a front elevation of the door, showing the ventilating-screenpartly open witha portion of the side piece of the door broken awa-y toshow the construction of the guide for the adjustable window sash andshowing a portion of the spring actuated roller in elevation and aportion of the netting and inclosing case broken away. Fig. 2 is aVertical section on the line 2 2 shown in Fig. 1. Fig. 3 is an enlargedsectionaldetail of the handle for manipulating the window sash andscreen, showing in full lines the handle engaging the lock-pins andshowing in dotted lines said handle swung into a horizontal position foradjusting the position of -the window sash and screen. Fig. 4 is anenlarged detail front view of the lower end of the window-sash, showingthe clamping-roll.. Fig. 5 is an enlarged sectional detailon the line 55 shown in Fig. 1; and Fig'. 6 is a detail cross-section on the line 6 6in lFig. 3, showing the handle engaging the locking-pins for holding thesash in closed locked position.

Similar letters'refer to similar parts wherever they occur on thedifferent parts of the drawings.

In the drawings, A represents an outside door for a house, on which A'A' are the upright stiles, as usual. The upper portion of the door isprovided with an opening B. (Shown in Fig. 2.) The lower portion of thedoor is provided with a longitudinal slotted recess A, (shown in Fig.2,),adapted to receive the window-sash C. In practice I secure to theinner portions of the upright stiles A' grooved metal bars D, in whichthe window-sash C is guided during its vertical adjustment.

C' is a glass pane secured to the sashC in any suitable or well-knownmanner. To the upper end of the sash C is attached the lower end of awire screen or netting E, the upper end of which is suitably secured toa springactuated roller F, similar in construction to ordinary springShade-rollers and need not here be described in detail. The saidspringactuated roller has each end of its springactuated spindle fsecurely attached to a bracket f', fastened in a suitable manner to theupper ends of the stiles A' A', as shown in Fig. 1.

The inside of the door is longitudinally slotted, as shown at A3 in Figs. 2, 3, and 6, and to the inside of the door is preferably attached ametal plate G, having a` Vertical slot g. (Shown in Figs. 1, 2, 3, and6.)

To the lower end of the window-sash C is secured in a suitable manner ablock H, to the lower end of which is journaled a roller (Shown in Figs.2, 3, and 4.)

In connection with this my adjustable screen-door device I use anadjustable clamping` device for securing the sash in any desiredposition relative to the door according to the amount of ventilationneeded, and such clam ping device is constructed as follows: It consistsof a preferably metal block I, secured to the sash-block H byscrew-bolts z' going loosely through the slots g and A3,respectively, inthe door-plate Gr and door A, as shown. In practice I provide the underside of said block I with antifrictional rollers I' l', adapted to rollon the outside of the slotted door-plate G, as shown in Figs. 1 and 3.To the block I is pivotally connected at lc a handle K. The innerpivoted end of said handle is provided with a cam projection or surfacek', which serves to frictionally clamp the roller 71, on the window-sashO against the interior slotted portion of the door when the said handleis swung to the position shown in full lines in Figs. 1 and 2. Byswinging the said handle to the position shown in dotted lines in Fig. 3the window-sash is liberated and may be vertically adjusted bymanipulating the handle K up or down, as may be desired. For the purposeof securely looking the window-sash in its highest position, as may bedesired at night on retiring, I make on the door-plate Glocking pegs orprojections g' (1', adapted to engage with notches or recesses 71: 7'7on the under side of the handle K when the latter is swung into lockedposition after the sash has been raised to its highest closed position,as shown in Figs. 3 and 6.

In using the device, supposing the sash is in its highest position andthe screen rolled up on the s1 )ring-actuated roller F and it is desiredto lower the sash and screen more or less, it is only necessary to swingthe handle K from the position shown in Figs. 1 and 2 to that shown bydotted lines in Fig. 3, when the operator by holding the handle canreadily move it downward the desired amount, thereby causing the sashand screen to be moved downward according' to the amount of ventilationdesired, after which the handle is swung to the position shown in Figs.1 and 2, causing the sash and the roller /L to be claniped in positionby the cam-shaped surface on the handle K, as shown in Fig. 2. If it isdesired to adjust the position of the sash and screen, it is onlynecessary to again swing the handle K to the position shown in dottedlines in Fig. 3, causing the sash to be released, after which it can bemoved up or down, as may be desired, and the screen correspondingly andautomatically wound upon the spring-actuated roller according to thedegree of ventilation desired. If on retiring at night it is'desired toraise the sash to the limit of its closed position, the handle K afterthe sash has been raised is swung to the position shown in Figs. 3 and6, in which the recesses 7a on the handle K are caused to be interlockedwith the projections g/ on the plate G, attached to the inside of thedoor, thus preventing the sash to be lowered from the outside-in fact,leaving the door in position as if provided with a` Having thus fullydescribed the nature, construction, andoperation of my invention, -Iwish to secure by Letters Patent and claim- 1. A door, having movabletherein, a glassoovereol sash, a screeninterposed between the upper endof said sash, and a spring-actuated roller arranged at the upper end ofthe door. a block connected to the lower portion of said sash, the doorbeing longitudinally slotted to receive the connecting means betweensaid block and sash, a handle pivotally connected to said block, andhaving a cam-shaped friction holding projection adapted to engage afixed part of the door to thereby hold the sash in a desired adjustedposition and a roller journaled in the lower end of the sashsubstantially as and for the purpose set forth.

2. A door having movable therein aglasscovered sash, a spring-actuatedscreen connected to said sash, a block attached to the lower portion ofsaid sash, a roller journaled in the lower end of the sash, a slottedplate secured to the inside of the door, the door being also slotted, ahandle pivotally connected to said block by means extending through theslot in the plate and door respectively, and a oam-shaped frictional''projection on said handle adapted to engage a suitable fiXed'part ofthe door to hold the sash in a desired adjusted position.

3. A door having a glass-covered sash- Vertically adjustable therein, aspring-actuated screen connected to said sash, a slotted plate attachedto the inside of the door, the door being also slotted, a block attachedto said sash by means passing through the slots in the plate and door,respectively, said block having antifriction-rollers adapted' to roll onsaid plate, a roller journaled in the lower end of the sash, and ahandle pivotally connected to said block and having a clampingprojection adapted to engage a suitable fixed part of the door to hold?the sash in the desired adjusted position.
